Answer:

Step-by-step explanation:
Here, we assume that point A is (-1, 0) and point B is (z, 2). Since angle BAD is 60°, we have ...
2/(z+1) = tan(60°) = √3
z = (2/√3) -1
Putting the value of z into the equation for the parabola lets us find "a".
2 = a(z +1)(z -5) = a(2/√3)(2/√3 -6)
Then ...
a = 2/(4/3 -12/√3) = (6√3)/(4√3 -36)
a = -(3+9√3)/52 ≈ −0.357470332079
I think number you are is 25 or 47 if not then it was worth a try
Answer:
R=18
Step-by-step explanation:
83 - 65 = 18,
18 + 65 - 83
so therefore r = 18
